Syed Mazharuddin witnessed the terrifying moment at Christchurch’s Linwood Mosque during a terrorist attack that claimed the lives of seven people.Mazharuddin said the gunman entered the mosque and began shooting indiscriminately at worshippers, causing them to flee.”People got feared and there was screaming around and I tried to take cover,” he told the New Zealand Herald .”By the time I took cover this guy came through the main entrance door and it’s a small mosque – there were about 60-70 people there.“Just around the entrance door there were elderly people sitting there praying and he just started shooting at them.”
